* headers: remove sched.h from interrupt.hAlexey Dobriyan2009-10-111-0/+1
| | | | | | | | After m68k's task_thread_info() doesn't refer to current, it's possible to remove sched.h from interrupt.h and not break m68k! Many thanks to Heiko Carstens for allowing this. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>
* tty: fix chars_in_buffersAlan Cox2009-07-201-3/+1
| | | | | | | | | | | This function does not have an error return and returning an error is instead interpreted as having a lot of pending bytes. Reported by Jeff Harris who provided a list of some of the remaining offenders. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* tty: nozomi, fix tty refcounting bugJiri Slaby2009-07-161-4/+8

* Remove low_latency flag setting from nozomi and mxser driversChuck Ebbert2009-06-241-2/+0
| | | | | | | | | | | The kernel oopses if this flag is set. [and neither driver should set it as they call tty_flip_buffer_push from IRQ paths so have always been buggy] Signed-off-by: Chuck Ebbert <cebbert@redhat.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* nozomi: Fix close on errorAlan Cox2008-10-131-1/+4
| | | | | | | | | Nozomi assumes the close method isn't called if open errors. The tty layer is different to other drives in this respect however. Pointed out by Denis J Barrow. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* drivers/char: replace remaining __FUNCTION__ occurrencesHarvey Harrison2008-04-301-1/+1

* char serial: switch drivers to ioremap_nocacheAlan Cox2008-04-301-1/+1
| | | | | | | | | | | | | Simple search/replace except for synclink.c where I noticed a real bug and fixed it too. It was doing NULL + offset, then checking for NULL if the remap failed.

* tty/serial: lay the foundations for the next set of reworksAlan Cox2008-04-301-11/+2
| | | | | | | | | | | | | | | | | | | | | | | | - Stop drivers calling their own flush method indirectly, it obfuscates code and it will change soon anyway - A few more lock_kernel paths temporarily needed in some driver internal waiting code - Remove private put_char method that does a write call for one char - we have that anyway - Most but not yet all of the termios copy under lock fixing (some has other dependencies to follow) - Note a few locking bugs in drivers found in the process - Kill remaining [ab]users of TIOCG/SSOFTCAR in the driver, these must go to fix the termios locking Signed-off-by: Alan Cox <alan@redhat.com> Cc: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* nozomi: fix initialization and early flow control accessFrank Seidel2008-03-101-18/+43
| | | | | | | | | | | | | | Due to some flaws in the initialization and flow control code kernel oopses could be triggered e.g. when accessing the card too early after insertion. See e.g. kernel.org bug #10077. The main part of the fix is a trivial state management making sure the card is realy ready to use before allowing any access.

* nozomi driverFrank Seidel2008-01-241-0/+1993
This is a driver to control the cardbus wireless data card that works on 3g networks. Greg Kroah-Hartman <gregkh@suse.de> did the initial driver cleanup. Thanks to Arnaud Patard <apatard@mandriva.com> for help with bugfixing. Thanks to Alan Cox for a lot of tty fixes. Thanks to Satyam Sharma <satyam@infradead.org> for fixing buildbreakage. Thanks to Frank Seidel <fseidel@suse.de> for a lot of bugfixes and rewriting to make it a sane Linux driver Thanks to Jiri Slaby <jirislaby@gmail.com> for a lot bugfixes, cleanups and rewrites that make it much more readable.
